From MMO:
So, for anyone looking for an easy strat for this fight, this is what my guild does, note I drive the construct.
To put it simply, I Fel Prison every ghost and we kill the boss before they break out. Put 1 line of fire between the raid and the blue portal. Drop the Fel Prison about 4 yards in front of the blue portal exactly 4 seconds before the Haunting Soul timer runs out on DBM. I don't know what the timing for this is if you use Big Wigs, though I'd assume it's similar. If you do that, you will catch all of the ghosts in the prison from the current wave as well as refreshing the stun on any ghosts you previously had trapped.
Other than that, have the whole raid stack in melee. There's no need to have ranged put any thought into positioning as you ignore the ghosts. Obviously you still run out with Gift of the Man'ari and the players that get it need to spread without going to Africa. If you want to extra special retard proof this strategy go ahead and assign major raid CDs to be used for each Dominator as there's no other points in the fight with any significant damage. This will ensure that even if someone is slow about running out of the group no one will die. Note AoE mitigation CDs such as Smoke Bomb, Spirit Link Totem and Power Word: Barrier are ridiculously good for this.
So yeah, ignore ghosts and do big dick damage. Handle the casters however you can with ranged interrupts and shit. I don't know about Druids and Monks, but Paladin Warrior and DK tanks can all help to some degree with getting the casters into cleave range.
As the construct, since I never had to stop hitting the boss except for when the Dominators spawned, I managed 280k dps last week. If your construct driver can do over 200k, you should have an easy time of it. This strategy relies on killing the boss before the 4th Dominator. You can live past 4, but the portals will swap positions soon after that, which will fuck you and may make it difficult to live for another 30 seconds.
